    • The systems and methods described herein provide a scientific and analytical basis for the following: (a) collective interpretation of the entire spectrum of chromatographic data, e.g., GC×GC two-dimensional data, with capability of operating at multi-resolution over bigger or smaller sub-regions of the two-dimensional data, (b) given two or more samples that are from the same source, and some samples from clearly different sources, quantitatively estimate where the fingerprint of the source lies, (c) given a source signature template, an unknown sample can be compared to decide whether it is related to, and if so, to what degree, to this source, and (d) given two source signature templates, the templates can be compared to determine how related is one source to the other.
    • 本文所述的系统和方法为以下内容提供了科学和分析依据:(a)对色谱数据的整个谱图的集体解释,例如GC×GC二维数据,具有在更大或更大分辨率下操作的能力 二维数据的较小子区域,(b)给出来自相同源的两个或更多个样本,以及来自清晰不同源的一些样本,定量估计源的指纹位置,(c)给定源 签名模板,一个未知的样本可以进行比较,以决定是否与之相关,如果是这样,在何种程度上,对这个来源,和(d)给定两个源签名模板,可以比较模板来确定如何相关是一个 来源到另一个。
